Description

MC-1R, MC-2R and/or [mu stimulation

The present invention relates to regulate neural mediation receptor expression by POMC (proopiomelanocortin) gene code, and the active component of regulating corresponding neurohumoral expression possibly.The invention still further relates to the purposes of compositions, said composition comprises at least a neural mediation receptor that pomc gene is encoded at the activated material of the expression of skin level, and a kind of method of screening this type of active component.

Current understanding to theme of the present invention:

Skin has sensory function, therefore is that individual information is originated at first.Peripheral nervous is responsible for the innervation of skin, and they have aixs cylinder, and its cyton distributes along spinal cord.The cutaneous nerve domination comprises, particularly comprises sensory nerve and autonomous sympathetic fiber.The epidermis free nerve endings is unique sensory fiber that gos deep into epidermis inside.There is a kind of important exchange between Skin Cell and cutaneous nerve.The synthetic neurotransmitter (paracrine approach) that acts on cutaneous nerve unit in a large number of Skin Cell.Skin Cell also has the corresponding receptor of some neurotransmitter that discharges with neurocyte and Skin Cell self; Therefore Skin Cell can be accepted these neurotransmitters and they are reacted.

The imbalance of skin aging and skin cell metabolism is relevant, it is characterized by that keratinocyte propagation reduces, keratinocyte differentiation imbalance, dead cell is piled up and the cutaneous nerve domination reduces.

((β-LPH) and β endorphins are the neuro hormone that proopiomelanocortin (POMC) single-gene produces for α-MSH), thyroliberin (ACTH), β lipotropin for α-MSH or α-melanotropin.They are mainly synthetic in hypophysis cerebri, but discovery (WintzenM, Yaar M, Burbach JP, Gilchrest BA.J Invest Dermatol (Dermatology research magazine) .1996 April is also arranged in many peripheral tissues such as skin; 106 (4): 673-8).Pomc gene and protein alpha-MSH, ACTH, β-LPH and β endorphins are expressed by hypodermal cell, fibroblast, Langerhans cell and epidermis cell, melanocyte and keratinocyte.

The receptor corresponding with these protein also expressed by Skin Cell.Melanocortin receptor 1 (MC-1R or MCR-1) is the receptor of α-MSH and ACTH, and melanocortin receptor 2 (MC-2R or MCR-2) is the receptor of ACTH, and [mu ([mu R) is the receptor of β endorphins.

In skin, α-MSH, ACTH and β endorphins suppress the synthetic of inflammatory cytokine IL-1, TNF α and IL-10, so they have inflammatory properties.And, these cytokines excite nerve synthetic (Moustafa M, Szabo M, Ghanem GE, Morandini R, KempEH, MacNeil S, Haycock JW, " Dermatology research magazine " (.J Invest Dermatol) .2002 December of hormone; 119 (6): 1244-53).Therefore, there is the negative oppositely control of cutaneous neurosis disease in the skin.

Known α-MSH and ACTH can regulate the melanin generation by acting on its corresponding receptor in melanocyte.α-MSH and ACTH are the inducers of melanocyte propagation.In addition, known β endorphins has the mitotic effect of the melanocyte of promotion, and the dendron that can increase melanocyte forms (Kauser S, Schallreuter KU, Thody AJ, Gummer C, TobinDJ, " Dermatology research magazine " (J Invest Dermatol) .2003 June; 120 (6): 1073-80).

Known α-MSH and ACTH are also synthetic by keratinocyte.These two kinds of protein induce skin keratin to form the propagation and differentiation (the Chakraborty AK of cell, Funasaka Y, SlominskiA, Ermak G, Hwang J, Pawelek JM, Ichihashi M., " biochemistry and biophysics's journal " (Biochim Biophys Acta) .1996 August 28; 1313 (2): 130-8).

The different cells of skin (keratinocyte, melanocyte and fibroblast) can synthesize other neurotransmitters, for example nerve growth factor neurotrophic factors such as (NGF).Keratinocyte and fibroblast produce the receptor of NGF, TrkA and p75NTR.By combining with TrkA, NGF induces the propagation of these cells, in case the keratinocyte apoptosis.As everyone knows, NGF can induce the neuron differentiation and make its survival; Therefore NGF is playing an important role aspect the maintenance neuron density.In addition, in mice, demonstrate the existence of POMCmRNA in the dorsal root ganglion neurons, this shows that melanocortin system, particularly α-MSH have participated in the peripheral nervous reparation.Therefore, α-MSH is played a role in the neurotrophy function (Gispen WH, Adan RA., " institute of NYAS newspaper " (Ann N Y Acad Sci.) on October 20th, 1999; 885:342-9, van der KraanM, Tatro JB, Entwistle ML, Brakkee JH, Burbach JP, Adan PA, GispenWH. " brain research with molecule brain research " (Brain Res Mol Brain Res.) on January 8th, 1999; 63 (2): 276-86).In addition, known β endorphins and its derivant can make the people produce the health and happiness sense by combining with the [mu of neurocyte.

Up to now, the professional once attempted to regulate neurohumoral releases such as α-MSH or β endorphins or simulated their function, with cutaneous homeostasis and/or improve the innervation of skin.

In addition, the professional attempts to solve the skin aging problem by not exclusively suitable different metabolic approach always.But still exist some new ways to demand urgently exploring now.

A previous patent application WO2007/039058 discloses opioid receptor antagonists has been used for reducing the overall purposes that the melanocyte Opioid Receptors is expressed.Another previous patent application US2004/0214851 discloses a kind of raising Opioid Receptors and has expressed to be used for the method for diagnosis and/or treatment (only being used for damaged tissues).These disclosed contents do not provide the method that solves the skin aging described in the context.
